DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box support for a lightweight stud which is suitable for attaching an outlet box to a lightweight stud.

[0002]

2. Description of the Related Art Conventionally, as a device for attaching an outlet box to a lightweight stud, there has been known a support fitting previously proposed by the present applicant (Japanese Utility Model Publication No. 5-26165). This support bracket allows the position of a box mounted on a lightweight stud to be easily adjusted. Then, when attaching this support bracket to the stud, align the long hole of the support bracket connected to the stud with the round hole of the box to be attached to this support bracket, and insert a screw for connection into these holes,
The cap nut was attached and connected.

[0003]

With such a conventional support fitting, the position of a box mounted on a lightweight stud can be easily adjusted. However, there has been a problem that the operation for mounting the box on the support bracket requires much time and effort.

[0004] That is, the work of screwing together the long hole of the support bracket and the round hole of the box is to support the box by hand with the holes aligned, and to further tighten the screw in each hole in that state. And then attach the cap nut. For this reason, it took time and effort to attach the box to the support bracket.

Accordingly, the present invention has been created to solve the above-mentioned problems, and a box supporting metal fitting for a lightweight stud which can greatly simplify a box mounting operation and stabilize a mounted box. The purpose is to provide.

[0006]

In order to achieve the above-mentioned object, a first means of the present invention is provided on a box support rod 1 having a substantially L-shape in plan view for supporting a wiring box Q, and comprises a lightweight stud. A box support fitting for tightening the connecting portion 3 which presses against the outer portion P1 of the opening P and the stud nut 2 which is locked to the inner portion P2 of the opening of the lightweight stud P with the fastening bolt 6 so as to be vertically slidable on the lightweight stud P. Along a longitudinal direction of the box supporting portion 4 bent and extended from the connecting portion 3 of the box supporting rod 1, a long hole 4A for engaging the connecting screw 7 for screwing the box Q is formed. A bent portion 5 is formed by bending the distal end portion of the box support portion 4 at a substantially right angle. And the insertion hole 5A and the box support 4 Lies in a continuous form and a long hole 4A.

The second means is that a connecting screw 7 attached to the outside of the box Q from the inside of the connecting hole Q1 opened in the box Q and a nut 8 temporarily fixed to the connecting screw 7 outside the box Q are provided in the box Q. It is to attach the nut 8 to the insertion hole 5A of the box support rod 1 after mounting.

The third means is to solve the problem by fixing the box supporting rod 1 mounted on the lightweight stud P by contacting the tip of the bent portion 5 of the box supporting rod 1 with the partition wall R surface. I do.

[0009]

Embodiments of the present invention will be described below.

The box supporting fitting of the present invention comprises a fastening bolt 6 for tightening a connecting portion 3 which presses against the outer side portion P1 of the lightweight stud P and a stud nut 2 which is engaged with the inner side portion P2 of the lightweight stud P. And is mounted on the lightweight stud P so as to be freely slidable up and down.

The connecting portion 3 is provided at an end of a box supporting rod 1 having a substantially L-shape in plan view for supporting a wiring box Q (see FIG. 1). The illustrated connecting portion 3 is connected to the lightweight stud P with two fastening bolts 6.
Can be appropriately changed. Then, a long hole 4A is formed along the longitudinal direction of the box supporting portion 4 bent and extended from the connecting portion 3, and a connecting screw 7 for screwing a box Q is locked in the long hole 4A.

On the other hand, a bent portion 5 is provided by bending the front end of the box supporting portion 4 at a substantially right angle. The bent portion 5 is bent toward the side opposite to the surface on which the box Q of the box support portion 4 is mounted, and is brought into contact with the partition wall R surface (see FIG. 1). Then, an insertion hole 5A is provided in the bent portion 5, and the insertion hole 5A and the long hole 4A of the box support 4 are continuously formed. Further, the head 7A of the connecting screw 7 which is temporarily attached to the connecting hole Q1 of the box Q in advance is inserted into the insertion hole 5A.
To lock the connecting screw 7 in the elongated hole 4A.

The connection screw 7 shown in FIG. 3 is inserted from the outside of the connection hole Q1 opened in the box Q toward the inside, and a cap nut 8A is mounted inside the box Q. In this case, the head 7A of the connecting screw 7 using the additional screw is locked in the elongated hole 4A of the box support 4 (see FIG. 2). Also,
The connecting screw 7 shown in FIG. 5 is inserted from the inside of the box Q toward the outside of the box Q.
B. In this case, the plate nut 8B is engaged with the elongated hole 4A of the box support 4 (see FIG. 4). The connection screws 7 and the nuts 8 are not limited to the illustrated example, but the point is that the box Q is provided in the box support portion 4 by using the insertion hole 5A of the bent portion 5 and the elongated hole 4A of the box support portion 4. Can be connected as long as they can be connected.

[0014]

According to the present invention, the above-mentioned configuration achieves the original object.

That is, according to the first and second aspects, the box Q can be mounted on the box support fitting of the present invention with one touch. As a result, much time and effort required for attaching the box to the supporting bracket, which has been required conventionally, can be remarkably saved, and the working time can be greatly reduced.

According to the third aspect, since the bent portion 5 abuts on the partition wall R, the box support fitting of the present invention is stabilized, and there is an advantage that the work of attaching a switch or an outlet to the box Q can be easily performed.

As described above, according to the present invention, various advantageous effects such as extremely simplification of the box mounting operation and stabilization of the mounted box can be achieved.
